Wireless Sensor Networks are an active research area in diverse fields like military surveillance, habitat monitoring, weather and others. In WSN, the sensor nodes have a limited transmission range, processing, storage capabilities and energy resources. In this paper, the authors illustrate the existing routing protocol ORMMA-WSN and analyze various parameters viz. throughput, delay, and network load by varying the number of sensor nodes and transmission power in a multi-sink scenario. Also, comparison has been made with AODV protocol. Analysis reveals that parameters are affected with increase in number of sensor nodes, transmitter power and ORMMA-WSN outperformed in throughput and delay with respect to AODV protocol.
